This last book in the Bible is made up of the correct response to the crucial problems with which people have been confronted over the generations, in trying to find meaning in their lives. The first mystery that troubles the minds of those who don't know God is the following: if an all-powerful, wise, and good Creator truly exists, why did He create a corruptible world? Why does He allow the Devil to act as he does so often, producing so much suffering among mankind, without intervening to put things in order?
The second common question follows: why does the righteous one so often have more problems, compared to the unlawful ones, who are constantly rebelling, and in spite of all that, they live a rich life and die without being punished ?
We won't be able to find the appropriate response unless we look at it from the Creator's perspective, even if only for a few moments. If we would only ask Him, He is ready to give us the answer through words of Scripture.
Besides the material universe, God created a world that is corrupt and is made up of angels and people, desiring that any of these beings would acknowledge Him and serve Him out of love, not out of fear or because they are obliged. Every created being is free to chose and to decide whom he wishes to serve (Joshua 24:15). See, I set before you today life and prosperity, death and destruction (Deuteronomy 30:15-20). Everyone's reward or punishment will be according to the choices he makes (Ezekiel 18:23).
